实验一:配置IP地址

1.实验环境

主机A和主机B通过一根网线相连

2.需求描述

为两台主机配置IP地址，验证IP地址是否生效，验证

同一网段的两台主机可以互通，不同网段的主机不能

直接互通

3.推荐步骤

1. 为两台主机配置P地址，主机A为10.0.10.10，主机B为10.0.11.11配置子网掩码

均为255.255.00

2.通过 ipconfig 命令验证主机IP是否生效

复制代码

C:\>ipconfig

FastEthernet0 Connection:(default port)

   Link-local IPv6 Address.........: FE80::2D0:58FF:FEA8:EE60
   IP Address......................: 10.0.10.10
   Subnet Mask.....................: 255.0.0.0
   Default Gateway.................: 0.0.0.0

Bluetooth Connection:

   Link-local IPv6 Address.........: ::
   IP Address......................: 0.0.0.0
   Subnet Mask.....................: 0.0.0.0
   Default Gateway.................: 0.0.0.0

C:\>ipconfig

FastEthernet0 Connection:(default port)

   Link-local IPv6 Address.........: FE80::290:21FF:FE09:2730
   IP Address......................: 10.0.11.11
   Subnet Mask.....................: 255.0.0.0
   Default Gateway.................: 0.0.0.0

Bluetooth Connection:

   Link-local IPv6 Address.........: ::
   IP Address......................: 0.0.0.0
   Subnet Mask.....................: 0.0.0.0
   Default Gateway.................: 0.0.0.0

3.通过 ping 命令验证两台主机是否互通

复制代码

C:\>ping 10.0.11.11

Pinging 10.0.11.11 with 32 bytes of data:

Reply from 10.0.11.11: bytes=32 time<1ms TTL=128
Reply from 10.0.11.11: bytes=32 time=4ms TTL=128
Reply from 10.0.11.11: bytes=32 time<1ms TTL=128
Reply from 10.0.11.11: bytes=32 time=3ms TTL=128

Ping statistics for 10.0.11.11:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 4ms, Average = 1ms

4.将子网掩码都改为 255.255.255.0，并重复步骤 2，步骤 3

1.将子网掩码都改为255.255.255.0

2.重复步骤2
